Cosmetics & Personal Care Industries
The growing cosmetics & personal care industry will have a positive impact on the colloidal silver market. Cosmetics & personal care products are exposed to bacteria and fungi, in particular during their manufacture or storage. Since cosmetics have a direct contact with human body, it is important to prevent their contamination with pathogenic microorganisms. In addition, the biological purity in the final products should be also ensured. For this purpose, silver nanoparticles have been also used. Silver nanoparticles can penetrate deep into the skin and remove from it any bacterial contamination, which inhibits the formation of acne. Silver nanoparticles have also been used in the production of toothpaste or oral care gels. Silver as an ingredient of such products at a concentration of 0.004% w/w is an effective factor in preventing the growth of bacteria that cause unpleasant oral smells and dental cavities.Ha et al in their patent provide a method of using silver nanoparticles as an ingredient in cosmetics dyeing mixture. The color is dependent on the nanometal structure. In the case of silver nanoparticles, a yellow color is mostly achieved. The authors report that one can use a combination of nanoparticles of silver and gold and thus get a yellow-red colour. The product can be used in dyeing of cosmetic foundations, eye shadows, powders, lipsticks, inks, varnishes or eyebrow pencils. According to Ha et al, the products with metal nanoparticles, unlike the conventionally used metallic pigments, are not harmful to human health, and may even have health benefits. A soap incorporating silver nanoparticles is also known and in 2013 the method for its preparation was patented. The authors report that thanks to the presence of silver nanoparticles, the product also has anti-inflammatory activity and protects the skin against the adverse effects of the microorganisms.
